if you give them the praise they deserve, they will always remember you appreciate them, and strive to give you a good service.
My son was a 7 day a week paper boy, and on a Sunday the paper bag was so heavy he had to have help from his dad to carry his bag. He delivered in all weathers for a full year. When he called at his customers for a Christmas tip, the biggest tips were from elderly people. The tighest were the ones who lived in five bedroomed houses, with two x four-wheeled drives on the front. One of whom, ( a local teacher) gave him nothing!. She also embarrased him by asking him why he was calling! Please bear this in mind when children call.
